Common Questions
Before you request support.
Can you help with a door that is not releasing or recognizing credentials?
Describe the affected door, credential type, controller or reader if known, and whether other doors still work. MD3 can review the access setup, power, and release workflow as part of troubleshooting.
Can access control be planned with the intercom and cameras?
Yes. MD3 scopes these systems together where the project requires coordinated entry communication, access permissions, and camera coverage. Compatibility and the existing installation determine the work required.
